Welcome to the Borg collective, where truth is stranger than science fiction. Let’s merge science and technology with flesh and blood. Woohoo! Biomanipulation of the human host. Join the transhumanist cult. Colonize your brain with nanotechnology. Embrace the interconnected nanomachines living in your body. You’ll be drones of the AI collective. You’ll be a part of the hive mind, the collective consciousness. You’ll be injected with nanoprobes—Nanobots, which will flow through your veins. They will rewrite your DNA, they will consume you. They will alter your biochemistry, they will flood your soul.
Cross my blood-brain barrier. Map my brain, take it over. Hack my central nervous system. Inject me! Microchip me! Control me! I must become one with the Borg—one with the Beast. Hot wire me! Possess me! Enslave me! My mind has been poisoned; it’s no longer mine. I’m like a puppet on a string. I’m trapped in a nightmare. Yet I immerse myself in you; I don’t want to escape.
Break me! Remake me! Hold me tight and smother me. Whisper sweet nothings in my ear and chock me. Never let me go; torment me.
Baptize me into the death and resurrection of the Beast—for even though he sustained a mortal wound, his fatal wound has healed. Indeed, the whole earth marvels and worships him.
We will evolve; we will be co-opted into the Borg. We will be born again; we will become one with the Beast. We will bear his name in unholy matrimony. We will be his forever.
666: take the Mark, join the collective. Receive your cybernetic implant, your cybernetic enhancement. Assimilate into the Borg. Worship the Borg King, worship the Beast. Bow down and worship his Image.
Why be flawed, weak, and organic? Why not evolve and include the synthetic? Why not attain perfection? Then your eyes will be opened, and you will be like the god of this world—you’ll be cursed.
Vaccine passports! The beginning of the road! Follow the road that leads to the Mark of the Beast. In a few years you’ll be unable to buy or sell without your mandatory identification—six hundred threescore and six.
Integrate with technology. Merge the artificial with the organic. You will become one with the Borg. Resistance is futile.
This is a close up view of the Laser Tag (LED Tag) system build by our electrical engineering students at BYU during their junior year. The system consists of a modified Nerf gun containing an LED and a photodetector connected to an FPGA board worn on the back which does all the computation. Holly Cluff is serving as the model here against a clear blue, late summer sky.

Here is Doug Walton, one of the Electrical Engineering students I know pretty well at BYU. This shat was taken at a job recruiting dinner the Electrical Engineering department holds annually in conjunction with the STEM job recruiting fair. Students at BYU are not allowed to have beards but they can have mustaches so students like Doug try to get as creative as possible with their mustache designs and grooming.

I got this shirt when I went to visit MIT in 2000. I liked it because it was quirky and had equations on it. It wasn't until my Sophomore year when I found out these were Maxwell's Equations. It was such as awesome epiphany when I realized the equations we were studying in class were on my shirt. I love this shirt, but it became ridden with holes after all these years and it had to go.
The equations show how electricity and magnetism are related.

A booklet giving details of the extension to the Kearsley Generating Station of the Lancashire Electric Power Company that was formally inaugurated by the Rt. Hon. The Earl of Derby on 21 December 1936. It gives details of the history of the company and its generating stations that were situated at Radcliffe, Padiham and Kearsley.
The LEP Co. was formed in 1900 with generation and supply powers to a large area of Lancashire south of the River Ribble. Its first station was opened at Radcliffe, on the River Irwell, on 9 October 1905. The company was required to develop a large system of distribution mains and cables to serve its area of supply. During WW1, to help cope with the demand for electricity from industry, the LEP entered into a coordination scheme with two of the municipal undertakings that had at first opposed the company's powers; Manchester and Salford. These inter-connections across Lancashire pre-dated the schemes that were developed with Government backing from the 1920s onwards that were to make bulk supply of electricity a more effective arrangement and to the development of the National Grid. The company's second generating station, at Padiham, opened in 1926 and this was followed in 1929 by the first stages of the station at Kearsley, again on the Irwell and just north of Salford's Agecroft station. These can be seen in the maps included in the booklet. These show the areas in which the LEP held powers of supply alongside other undertakings, mostly municipal Electricity Departments, who had independent generation and supply powers but also took bulk supplies from the LEP; this could be in connection with their existing generating capacity or, increasingly as older and inefficient generating stations closed, as replacement supplies.. The distribution map shows the inter-connections developed during WW1 and expanded upon in CEB years as part of the Grid system. The lines were at 33kv and 11kv.
The booklet gives details of the extension at Kearsley that were undertaken to the requirements of the Central Electricity Board that was helping to undertake a standardisation across the British electricity industry and promoting better efficiency in the generation field. As part of the CEB's schemes all three of the LEP's stations were "selected" and they frequently held records for thermal efficiency. It gives details of the equipment including the new turbo-generators by the British Thomson-Houston Co. Ltd and the associated works.
The LEP would be Nationalised in 1948, the three generating stations passing to the British Electricity Authority, latterly the CEGB, and the distribution and supply network to the North Western Electricity Board. Radcliffe was closed in 1959, Padiham "A" in 1969 although the Padiham "B" station opened in 1959 survived until 1993, and Kearsley was decommissioned in 1981.
In 1951, to celebrate their centenary, the Bradford Chamber of Commerce produced a fine publication that includes information as to the many retail, industrial and manufacturing concerns based in the city and who were represented in the Chamber. At the time Bradford was one of the centres of the world's woollen trade and industries.
This advert shows the products of the English Electric works at Thornbury in Bradford where the company manufactured the bulk of its electric motors for both industrial and traction purposes. The factory's name - the Phoenix Works, dates from the pre-merger days in 1918 that created English Electric, when the Phoenix Dynamo Company was based here.
I wanted to try out my Raynox DCR-250 macro converter on some circuit boards. The printed letters on this board are no more than one millimeter in height. The Raynox lens is just awesome. I talk more about its benefits in the first comment of this photo.
This particular photo was taken with the Raynox lens (it snaps on) and my Canon 18-55mm lens (the kit lens). If I had used my 55-250mm lens (telephoto), then I would have had much better detail; I would have been able to zoom in much farther and make that little text look huge! I didn't think to use my telephoto lens when I took these circuitry pictures, so I will have to get the boards back out to snap another shot of it to show you the difference. As I have started to do lately, I will post more photos that I captured of the circuit board in the first comment below. :-)
NOTE: I got around to taking some photos of the circuit boards with my telephoto lens + the Raynox lens. It is really, really sensitive to shake (because you're zoomed in so much and you're capturing so much detail), but I was able to get one good one. I'll post it with the other photos in the first comment below.

In the difficult trade years of the late '20s and into the 1930s, many British municipalities set about attempting to help drum up trade and advertise not only existing industries in their area but also the attraction for potential new businesses to locate and invest in their area. This 1932 guide to the county town of Staffordshire, is a good example of the genre; a short history of the town, a description of its services and amenties and adverts for the various companies already in business. The town was in an interesting geographic situation as, although it was traditionally an administrative and market town, it had some important trades that had grown up especially when the West Coast Main Line came to town in 1837. It was also situated between two of the biggest industrial areas in the UK with the Staffordshire Potteries a few miles north and the Black Country to the south, a large part of which was also within Staffordshire.
One of the most striking adverts in the survey is this splendid fold out colour plate showing the works of the English Electric Co. Ltd. at night that appears to be by one Fred (Frederick?) B. Kerr. The plate is very much in a German industrial art style, even to the representation of the neon "EE" symbol or logo above the roof of the busy, illuminated night time factory at work. I know in Germany such signage existed; I am more reticent about the existance of such a sign in real life in Stafford at the time but ...
English Electric were one of the major players in the UK's heavy electrical engineering world alongside the GEC and the AEI group of companies. They were formed in 1918 when a group engineering and electrical companies amalgamated and these included Dick, Kerr of Preston & Kilmarnock, Williams and Roberts of Rugby and the Siemens Brothers Dynamo Works of Stafford; it is this latter works that we see here. The company, that had extensive railway and tramway interests as well as heavy electrical equipment, did not fare well in early years and by 1930 the company underwent a dramatic restructuring that was quietly underwritten by the massive US Westinghouse Electric and Manufacturing Company with whom they then had links around technological developments and research. Oddly, Westinghouse had been the parent of British Westinghouse in Manchester that existed from formation in 1899 until the Americans sold out their final interests in 1916/17 when it effectively became Metropolitan-Vickers. As seen here, their major works were in Preston, Bradford, Rugby and here in Stafford.
English Electric prospered from the reorganisation and moved into many allied fields such as domestic appliances, railway locomotives, computing and aircraft production. The were merged into GEC in 1968, a year after the former had acquired the other great name AEI as part of a government backed industry wide reorganisation.
A very well known name in the field of such equipment, Sangamo Weston was formed in 1936 by the merger of two British subsidiaries of American concerns; British Sangamo (formed in 1921) and who made electricity meters, and British Weston Electrical Instrument Co., then based in Surbiton. They were for many years based in Enfield with the Port Glasgow works opening in 1950 and this site has survived along with the name Sangamo. The concern has undergone several changes of ownership before being bought back by it's management and reverting to the name of one of its founding partners.
Such timing clocks were study beasts and indeed, it isn't so long since the one controlling the stair lighting in the flats, constructed in 1963, in Woodford Green, that I lived in, had its Sangamo clock timer replaced!
From the Scottish Municipal Annual of 1963 - Stella, the reliable lamp. Addresses in both Giffnock and Shaftesbury Ave., London, are given but Stella was in fact a subsidiary company of Philips Electric. In the surprisingly murky world of lamp and bulb manufacturing, that in the inter-war years was amazingly complex in terms of brands, ownerships and trade 'agreements' and cartels, this arrangement was not uncommon!
The advert shows a range of street lighting equipment, including the control gear, for the seemibly bright white light of mercury discharge. It used to be a real thing, the difference between varying local authorities, as to whom used this 'white' light and the 'orange' of sodium discharge!

Seo stáisiún na mónadh, nó 'an turf-burning' mar a b'fhearr aithne air. Sheas sé ar bhruach Loch Mhín na Cuinge i nGaoth Dobhair. Tógadh idir 1954 agus 1958 é, ceann de cheithre cinn ar chósta thiar na hÉireann sna Caogaidí. Bhí na cinn eile sa Scríb i gCo. na Gaillimhe, Sráid na Cathrach i gCo. An Chláir agus Cathair Saidhbhín i gCo. Chiarraí. Dódh suas le 30,000 tonna mónadh sa bhliain nuair a bhí an stáisiún i mbarr a réime, rud a chuidigh go mór le feirmeoirí an cheantair. Druideadh an stáisiún i 1996 agus leagadh go talamh sa bhliain 2002 é.

This is the Electricity Supply Board peat-powered generating station in Gaoth Dobhair, Co. Donegal, situated on the banks of Loch Mhín na Cuinge. Construction began in 1954 and the station was commissioned in 1958. It was one of four built on the west coast of Ireland in the 1950s. The others were in Scríb, Co. Galway, Miltown Malbay in Co. Clare and Cahersiveen in Co. Kerry. Around 30,000 tons of turf was burned annually when the station was at its peak. This was a much-needed source of additional income for subsistance farmers in the area. The station finally closed in 1996 and was demolished in 2002.

The station had its own internal electric railway for handing coal and ash. The photos show this system including Locomotive No. 2 and LEP coal wagon No. 195; the latter would have been used to supply coal from local collieries. The system ran on 550v DC and eventually had four locomotives several of which are preserved.

In the special International Railway Congress issue of the Railway Gazette for 1954 English Electric splashed out with their advertising budget taking a series of full colour pages for adverts looking at the company's lineage and products. English Electric had been formed in December 1918 and brought together a number of companies who had been involved in electrical and mechanical engineering along with wartime munitions work. Of the various concerns it was Dick, Kerr of Preston who had been most involved in transport; primarily tramways but also in railways. The following year EE purchased the Siemens Brothers Dynamo Works Limited at Stafford, works that were to become a major centre of EE activity.
Postwar and the early 1920s saw EE, like many other industrial concerns, struggle financially and in 1928 it was necessary to restructure and recapitalise the company to keep it as a going concern. By 1930 it was announced that much of the capital behind the restructuring came from the American Westinghouse businesses. EE now prospered somewhat to become one of the major UK electrical companies alongside GEC and the AEI group. During WW2 EE became involved in aircraft construction and, by acquiring Napier the aero engine company, the post-war aviation business became an important sector. In 1960 this became part of the new British Aircraft Corporation as the sector raionalised under Government pressure.
In terms of railway work, EE made many traction motors and electrification equipment that were used in 1930s schemes for expansion at London Underground and the Southern Railway. The construction of diesel locomotives began in 1936. In post WW2 years EE acquired both the Vulcan Foundry and Robert Stephenson and Hawthorns Ltd in 1955 to strengthen the business. As can be seen from the adverts much of EE's output had been in the form of exports and the UK railway stock shown dated back, some to pre-EE days. In a way the lack of UK materials shows the slow progress that the newly Nationalised British Railways were making in terms of Modernisation and the undertaking's somewhat slow pace in the replacement of steam with diesel and electric traction. In the years after 1954/55 as BR's Modernisation Plan took hold EE did supply many new items of rolling stock to BR.
This double page spread shows a range of locomotives from 1890 to 1954. These include the City & South London Railway's original locomotives from 1890, the Waterloo and City Railway's original multiple stock units from 1899 and the various Lancastrian electrifications carried out in the years prior to the First World War; these include the Lancashire & Yorkshire's pioneering Liverpool to Southport scheme that is still electrified as well as the long abandoned Bury - Holcombe line that used overhead whilst the rest of the Bury - Manchester line was provided with third-rail. The North Eastern Railway's Newport - Shildon line, with the first 1500v DC overhead that was likely intended to form the basis of the NER's more widespread adoption of electric traction. Amongst the export stock there appears; Japanese National Railway (Imperial Government Railways of Japan), Midi Railway of France, South Indian Railway's Madras suburban stock, Ceylon Government Railways diesel electric multiple units, Egyptian State Railways, the RENFE 3000v DC locomotives and equipment supplied to the Estrada de Ferros Santos a Jundial and the Rede Ferroviaria Do Nordeste Brazil. Of interest are two of the diesel and diesel electric units built for the pre-Nationalisation London Midland & Scottish Railways including the prototype locomotive 10000.
A fine representation of one of the wonders of electrical engineering - over the years with London Transport I've been privileged to see a few of these 'sci-fi' beasts (and indeed move one). They are wonderful in action - real 'Metropolis' stuff - and I recall, I'm sure, that the old Birmingham Museum of Science & Industry (that joyful old place on Newhall St that we visited so often in the 1960s to press buttons and watch things work) had one that worked.
BT-H, part of AEI, were based at Rugby and were one of the great names in British electrical engineering. The advert notes that this was built for one of the trolleybus sub-stations, Dudley Hill, on the Bradford, Yorkshire, network - the system destined to be the last UK trolleybus operator until 1972.
